Abstract:
AIM To prepare silymarin solid dispersions and to evaluate the dissolution rates of five constituents.METHODS Taking F68 and PVPk30 as a combined carrier,the solid dispersions were prepared by solvent fusion method.Then the effects of combined carrier ratio and drug-carrier ratio on dissolution rates of silybin,isosilybin,silydianin,silycristin and taxifolin were investigated.RESULTS The optimal conditions were determined to be 1 ∶ 3 for combined carrier ratio,and 1 ∶ 5 for drug-carrier ratio.These five constituents displayed much higher dissolution rates in solid dispersions than those in raw medicine and physical mixture (silymarin-carrier).CONCLUSION Solid dispersions can significantly increase the dissolution rates of effective components in silymarin.
